try

            {

                DataTable dt = new DataTable();

 

                dt.Columns.Add("ID", typeof(int));

                dt.Columns.Add("Name", typeof(string));

 

                DataRow dr = dt.NewRow();

                dr["ID"] = 100;

                dr["Name"] = "Bala";

                dt.Rows.Add(dr);

 



               // dataGridView1.DataSource = dt;    



            }

            }

 try

                oconn.Open();

 

                SqlDataAdapter oda = new SqlDataAdapter("Select ID,Name from employees", oconn);

                oda.Fill(ds);

                dataGridView1.DataSource = ds.Tables[0];
